Altrincham, England Application November 10, 1937, Serial No. 173,788 InGreat Britain May 20, 1936 9 Claims.

The invention relates to the manufacture of cartons, barrels and thelike, and more particularly to such articles of the kind in which thebody part is made by winding a length of paper or the like and securingthe several laps or thicknesses together by means of an adhesive.

Fully automatic machines are known for making the bodies of suchcartons, barrels or the like but owing to the high initial cost of suchmachines large quantites are still made by a slower process of windingonto a mandrel involving the services of at least two operatives.

The object of the invention is a simple and improved method of and meansfor producing such bodies.

The invention consists in the method of making wound bodies for cartons,barrels and the like, wherein the paper, or other material is fed to amandrel which while stationary or substantially stationary, grips theends of the paper, then revolves to wind the same in a predeterminednumber of turns or laps, an adhesive being .applied to the paper as itis fed to or while on the mandrel and the paper being severed to therequired length, the mandrel being further rotated to secure the outerend of the paper and the body being finally removed from the mandrel bystopping the rotation of the mandrel and causing it to collapse indiameter and at the same time to release the inner end of the paper.

Apparatus for carrying out the method according to the inventioncomprises improved details of construction of the mandrel, of mechanismfor applying the adhesive or releasing and removing the finished bodyand of timingeach stage of the cycle of operations.

F g. 11 is an inverted plan showing a trip catch connected by cable to apart of the valve control mechanism.

Fig. 12 is a detail view of part of the mechanism below the table.

As illustrated, there is a main frame carrying a fixed shaft H having along overhang on which shaft the mandrel described in detail later isrotatably mounted, the purpose of the overhang being to leave one end ofthe mandrel free for the subsequent removal of the finished body. At thebase of this shaft is provided a driving flange i2 to which the mandrelis bolted, which flange is rotatably mounted on suitable ball bearingsand embodies a toothed flange l3 for chain drive and a hollow drum Mwhich internally forms a brake drum. At its outer end, the shaft Itcarries. another ball bearing IE on which the other end of the mandrelis supported.

The main frame IU- comprises two transverse members and threelongitudinal members, which latter are indicated as Ella, liib and Mic.The mandrel, table and working part of the machine are arranged betweenlilaand llib while the driving and timing mechanisms are mainly at oneside of the machine between the members lfib and Mic. The members Ebband H10 carry brackets Hid in which the fixed shaft H is supported andsecured. Below the shaft H is mounted a driving shaft It carryinga'clutch ll, one part of which is secured to the shaft while the otherpart is provided with a further chain wheel I9 adapted to be coupled bya chain to the toothed flange 53 of the mandrel. In front of the drivingshaft i6 is a counter-shaft 20, mounted in suitable bearings on themembers lllb' and I00, which shaft is provided with fast and loosepulleys 2i and a chain wheel 22, which latter is coupled by a drivingchain to the chain wheel l8 of the clutch. Instead of providing fast andloose pulleys for belt drive from a power shaft an electric motor may bemounted on the frame with positive drive to the counter-shaft. Fixed tothe counter-shaft 26 is also a chain wheel 23 which is connected by adriving chain to a hydraulic pump 24. Fixed to the driving shaft it is atiming chain wheel 25 coupled by chain to a single start timing worm 26rotatably mounted on the countershaft 20 which timing worm 26 isconnected by a further chain to a crank-shaft 27! mounted in furtherbrackets at the front end of the members I02) and I110. The timingsh'aft, crankshaft, driving shaft and mandrel rotate at the same speedin the same direction. Engaging and driven by the chain between thedriving shaft and timing worm is a governor a. Adjacent to the pump 24is a tank 28 for the hydraulic fluid and a hydraulic pressureaccumulator 29. Immediately in front of the countershaft 2 0 is a fixedguide bar 30 on which is slidably mounted a compound cross head 3!having on its underside a lug normally in mesh with the threads of theworm 26 (see Figs. 3a and 8). Slidably mounted in the crosshead is ashaft 32 which is connected to the crank of the crankshaft 21 by aconnecting rod 33 of adjustable length. The crosshead 3| is adapted tobe rocked about the guide bar 39 so that its lug may be disengaged fromthe worm and this movement is obtainable for any position of thecrosshead on its guide bar by means of a rocking bar 34 adapted on theone hand to engage a rod 35 depending from the crosshead and itself tobe rocked by an arm 36 secured to the clutch control arm 31. The clutchcontrol arm 31 is secured to the end of a shaft carrying the clutchcontrol fork 38, and is operated by a hydraulic ram 31a, the controlvalve of which are operated by a tappet 46 described later. On the otherend of the clutch fork shaft is an arm Me connected by a suitable linkI4b including a cushion spring l4d (shown in Fig. 7), to the brake camlever 94c, operating the brake shoes within the brake drum id, to applysuch shoes simultaneously with disengagement of the clutch. Thecrosshead 3! is connected by a wire cable 3 la to a counterweight 39which acts to return the crosshead to the starting end of its guide barwhen its lug has been lifted out of the threads of the worm.

An adjustable stop 40 with cushion spring is provided on the guide bar35 which latter is calibrated for setting the number of turns of themandrel. On the end of the crosshead shaft 32 is a striker head 4| whichis adapted to operate a group of 5 tappets 42, 43, 44', and 46, whichexcept for 45 operate hydraulic valves arranged in pairs of inlet andoutlet, all of which mechanism is mounted on brackets above the clutch.The tappet 45 merely operates a catch described later. The valves ofeach pair are operated by a rocker having a spring at one end ofsufficient strength to pull the rocker and hold the outer valve normallyopen. The ends of the rockers are adapted to be engaged by the tappetswhich push back the rockers, the first part of their movement closingthe outlet valve and then following on to opening the inlet valve. Thevalves controlled by the tappets 42 and 43 are arranged for simultaneousoperation. by fingers 41 attached to a shaft carrying a striker plate48, the edge of which is stepped and radiused to correspond with strokeof the striker in its different posi-- tions due to the radial movementof the connectingrod. The striker engages directly with the ends of thetappets 44, 45 and 4B and it is to be noted that the spacing of thesetappets is the same as the pitch of the worm, with a blank between 44and 45. The tappets of all the valves have return springs while tappets42, 43, 44 and 46 have catches 42a, 43a, 44a and 46a respectivelypivotally mounted on a fixed rod 41a. The tappet 44 carries an arm 44badapted to engage a trip arm 4213 on the catch 42a. The catch 43a has atrip stud 43b adapted to engage beneath and trip the catch 44a and alsohas a trip arm 43c adapted to be engaged by an arm 45a on the tappet 45.The catch 46a is adapted to be tripped by an arm 4% having a wire cable,the other end of which is connected to a trip pawl 88 described laterand operated with the return movement of the feeding table.

The feeding table comprises a carriage 50 mounted within an adjustabletable which comprises side members 5i and 52 supported on and secured tocross members 53, on the underside of which are front and rear brackets54 and 55 carried on a pair of feed screws 56 which in turn aresupported in brackets 51 on transverse frame members 58 arranged betweenthe main frame members 1 5a. and I01), previously described. The frontbrackets 54 are screw-threaded to engage the threaded portions 59 of thefeed screws which are arranged to be rotated together by means of ashaft 60 and pairs of skew pinions 6|. This arrangement enables thetable to be moved towards or away from the mandrel so that differentdiameters of mandrel may be used. At the mandrel edge of the table is aglue trough 62 in which is mounted a glue roller 63 connected bysuitable driving means to an electric motor 64.

Across the top of the glue roller is a scraper knife 0 65 to provide therequired thin film to be applied to the paper. Across the table in frontof the glue trough is an angle iron 62a which forms a rest for theoverhanging end of the top plate 14 of the adjustable feeding table,described later. At the front end of the adjustable table is a roller 66to hold a loop of the paper. A guillotine knife 61 is mounted across thetable, the end arms of the knife being pivoted on the inside of brackets68 fixed on top of the side members 5! and 52. Also pivoted to thebrackets 58 and: on the outside thereof are lever arms 59 carrying apresser bar 10 which is adapted to be lowered onto the paper to causethe latter to engage the top of the gum roller. Mounted on the sidemember 52 is a hydraulic ram 10a and with return spring 101), theposition of which ram is connected to the end of one arm 10d of theguillotine. Alsoconnected to another arm We of the guillotine is acompression. spring 106 which is arranged so that the end thereofconnected tothe said arm Hie moves over a dead centre position duringoperation of the guillotine thus imparting a snap action to the latter.

The carriage 50 of the feeding table comprises longitudinal members 50aand 50b connected together by a wooden beam H, angle iron Ha and tirerod lib. Between the beam H and angle iron Ha is a trough 12 in whichare mounted two shafts carrying a pair of cutter discs 73. Sheet metalplates 14 and 15, secured to the longitudinal members, form the top ofthe carriage on which the paper rests, the plate 14 overhanging beyondthe beam H and the ends of the longitudinal members. Hinged above theplate 14 is a top plate 16 the transverse edge of which is level withthe transverse edge of the plate 14 and forms a nip and guide for thepaper. Behind the trough is a cross bar 11 carrying a plurality ofinclined spring loaded grippers 18 which rest on. the paper.

Below the adjustable table is a stirrup 19 connecting the ends of thelever arms 69, which stirrup is weighted and connected to the piston ofa hydraulic ram 80.

Secured to the front cross member 53 are a pair of pulleys 81 over whichpass cables 82 carrying weights 83 and anchored at their other ends tothe beam H. A shaft 84 is mounted between the members 5| and 52 andanchored on a small pulley 84a is a cable 85 connected to the piston rod86 of a hydraulic ram 81. On the rod 86 is a collar 86a which isprovided to engage a trip pawl '88 (see Fig. 11) connected by cable tothe arm 46?) of the catch 46a. On the shaft 84 are two larger pulleys 89to which are attached and on which are wound cables 90 connected attheir free ends to the tie bar 'II lb.

The mandrel itself is a hollow cylinder and is collapsible. It consistsof three parts, one a semi-circular part 9I, another a nearlysemicircular part 92, hinged together longitudinally and a third andnarrow part 93, hinged to the free edge of the semi-circular part andoverlying the edge of the other part. 92 and adapted to be movedoutwards when the two main parts have hinged upwards. Theunderlap 92a ofthe main part 92 is bent to form a support for the overlap of thesmaller part when the mandrel is expanded to its cylindrical form.Within the cylinder is a shaft 94 mounted on the larger part 9| andcarrying several levers 95 arranged along the length of the mandrel andengaging cam faces formed on the edge of the partitions 96 forming partof the built-up structure of the part 92. Return springs 95a areattached to the levers 95. The hinged joint of the two major parts ofthe cylinders are constructed to form a jaw 91 to receive and grip theend of the paper, for which purpose a rubber or leather insert may beprovided so that various thickness of paper can be used.

As some of the operations, such as the feeding in of the paper at thestart, require that the mandrel shall be stationary or nearly so, thecentrifugal governor 25a is provided, geared to the mandrel drivingshaft as previously described,

' such unit controlling the movement of certain controlling mechanism.The centrifugal control mechanism associated with the governor comprisesa cranked arm 90 adapted to rest on the periphery of a wheel 99 when thelatter is rotating, the wheel moving axially by the operation of thegovernor weights when the speed of revolution falls to a predterminedlimit, allowing the arm to fall down behind the wheel. This arm 90 issecured to a mandrel stop lever I00 which is thus held back until themandrel has slowed down. This lever I00 is shown in Figs. 6 and 7, andhas a sliding extension IOI, loaded by a compression spring I02 withadjustable extension stop I03. Incorporated in the lever is also anadjustable stop I04 and a dash pot I05.

The upper end of the lever extension IOI has a nose I06 adapted toengage a projecting lug I01 secured to the mandrel driving chain wheelI3,

previouslydescribed. Also attached to the upper end of the leverextension IOI is a catch box I08 in which is slidably mounted the catchend I09 of a catch link IIII, such catch end being slidable on its linkagainst a cushion spring I I 0a. The end of the link H0 is connected toalever II I of a valve controlling a. hydraulic ram cylinder I I2, whichis pivotally mounted on a bracket I I3 above the driving flange of themandrel. The end of the ram plunger I I4 is shaped to engage a stud I I5 (see also Fig. 5) carried by an arm I I6 secured to the shaft 94within the mandrel. Behind the ram cylinder H2 is a stop I" and a springH8 but when the ram piston is withdrawn as shown in Fig. 6 a cam II9 onthe plunger II4 engages a pin I20 on a fixed arm I2I and holds the ramend clear of the path of rotation of the stud H5 against the action ofthe spring H8. The ram plunger has a return spring I22 and a laterallyprojecting pin I23, adapted to engage the catch end I24 of a linkconnected to a lever I25of a valve which controls the ejector ram I31described later. The valve levers III and I25 have return springs I Ilaand I2'5a. A small bracket I26 carried a trip member I2'I having a pinI28 adapted to withdraw the catch end I24 from engagement with the pinI23. This trip member is connected by a wire cable I29 (see Fig. 4) to alever described later and operated by the ejector when it reaches theend of its travel. Behind the lever I00 is a cam I30 adapted to withdrawthe lever for disengaging the nose I06 from the lug I01, which cam ismountedon a shaft I3I having at its other end an arm I32 connected bylink I33 to the brake operating link I4b which, as dey scribed earlier,is connected to the shaft on which the clutch control fork, 38 ismounted. Attached to the plunger II4 of the ram is a wire cable I34connected to a catch I35 controlling the valve I36 for the tableoperating ram 81.

The ejector mechanism comprises a hydraulic ram I31 (see Fig. 1)connected by cable I38 to a compound pulley I39, to the larger diameterof which is attached a cable I40, which cable passes over a suitable:guide pulley MI and attaches to an ejector slide I42 mounted on rollersrunning on rods I43 below the mandrel. Another end of the cable I44returns over a similar guide and is attached to a compound pulley I39asimilar to I39, the smaller diameter part of which is connected by acable I 45 to a return spring I46. The

ejector slide has a raised plate I41 having a curved upper edge adaptedto lie just clear of the mandrel surface and engage the edge of thecarbon wound thereon. The lever of the valve I36, which is connected tothe cable I29 as already described, has an extension I48 adapted to beengaged by a projection I49 on the ejector slide.

I Underneath the table and secured to the frame member 53 is a pivotedlever I50 (see Fig. 12) connected by wire cable I5I to a trip lever I52(see Figs. 6 and 7) pivoted on the shaft I3I and having its end behindthe catch end I09. The lever I50 has an adjustable projection I53adapted to be engaged by the edge of the plate M of the carriage 50 ofthe feeding table.

The valves and their respective rams areconnected by suitable pipes toeach other and to accumulator 29 and reservoir 28.

At the back of the machine and between the members Ma and III!) of theframe is a tie bar I54 on which are pivoted pairs of levers carryingfeltcovered pressure rollers I55 and I56 adapted to engage the mandreland to hold the paper down thereon as it winds on. The pressure rollersI55 is operated by a hydraulic ram I51 having return springs I 58 andthe pressure roller I56 is operated by a hydraulic ram I 59 and returnsby its own weight. The roll of paper I60 is shown in Figs. 1 and 2looped round the roller 66 already described, and a further roller IBI.The roll of paper is mounted on an axle having flanged ends which restson the edges of inclined tracks I63 secured to the main frame. Insteadof the cutter knives I3, blade knives may be fastened to the bar I0 soas to project downwardly against the paper and sever it as it passesunderneath the bar.

The valve controlled by the tappet 42 contro s the ram 80 which operatesthe presser bar I0. The valve controlled by the tappet 43 controls thetwo rams I51 and I50 which operate the pressure rollers I55 and I56. Thevalve controlled by the tappet 44 controls the ram 10a which operatesthe gui-llotine knife 61 and also through theza'rm44b pushes back thetrip arm 42b lifting the catch 42a and releasing the valve controlled bythe tappet 42. The tappet 45 through its arm 45a operates the trip arm430 to lift the catch 43a which releases the valve previously operatedby the tappet 43 and at the same time, through the trip stud 43b it alsolifts the catch 44a and releases the valve previously operated by thetappet 44. The Valve operated by the tappet 46 controls the ram 370,which operates the-clutch control-forks 38 and through the linkMia-simultaneously operates the brake arm I40.

In operation, it must be assumed that themandrel is in the collapsedposition so that its hinged jaw 91 is open as shownin Fig. 5. The edgeof the paper is projecting beyond the edge of the plate 14 where it hasor would have been cut by the guillotine knife 61, the carriage 50 beingin the position shown in Figs. 1 and 2. The lug ID! of the mandrel chainwheel is in engagement with the nose I06 and has depressed the extensionIOI of the lever I to its lowest position where its end is in engagementwith the-adjustable stop I04, by which latter the position of themandrel can be adjusted so that the jaws 9'! of the man drel are on thecorrect level to receive the paper. The drag of the clutch checked bythe brake holds the mandrel in this position. The mandrel is heldcollapsed by reason of the catch end I09 having been pulled down withits catch box which is fixed to the part IOI, thus holding down thevalve lever III which admits pressure fluid to the ram H2. Thecrosshead-3l will be in the position shown in Fig. 3a, but with its luglifted clear of the feed screw 26 by the clutch lever 31.

The cycle of operation starts by the operation of the valve I36 to admitpressure fluid to the ram 81 causing the'table 50 to come forward untilthe bar 'II reaches the angle iron 62a. The-edge of the paper projectingbeyond the plate '14 will have entered the jaws 91 of the mandrel. Atthe end of such movement the end plate' I4 of the table 50 strikes theprojection I53 which through the cable I5I lifts the catch end I09through the lever I52 allowing it to rise to the position shown in Fig.6. This allows the valve lever III to rise operating the valve toexhaust the pressure from the ram I I2. The mandrel is then closed bythe action of its spring 95a to grip the paper. The piston of the ram II2 through the cable I34 has pulled back the catch I35 to release thelever of the valve I36 which then allows the table to return by itsweight 83. As the table 50 reaches the end of its return movement thetrip pawl 88 is engaged by the collar 860. which is connected by cableto the arm 46b. The trip pawl pulls the arm 46b and lifts the catchpiece 46a which releases the valve operated by the tappet 46 controlling the ram 31a to engage the clutch'and release the brakesimultaneously. At the same time the cam I30 is rotated by the lever I32connected to the brake link I41) and pulls the nose I06 from under thelug I01. At the same time also the lug of the crosshead 3I is loweredinto the thread of the feed screw 26.

The mandrel now commences to revolve, winding the paper onto itselfwhile the crank commences a forward stroke of the rod 32, the strikerhead M of which soon engages the striker plate 48 which through thefingers '4 pushes back the tappets 42 and 43. The valves operated bythese tappets respectivelycause the 'presser bar I0 to descend and thepressure rollers I55 and I56 to press against the mandrel. The paper isthus brought down by the bar I0 onto the gum roller, which iscontinuously driven and gumming of the underside of the paper commences.This delay allows for the first turn of the paper which forms the insideof the carton not to be gummed. The mandrel continues to revolve and thestriker head reciprocates while being also moved along by its feed screw26, but apart from making contact with the steps of the plate 48 it doesnothing until it reaches the tappet 44. When it engages the tappet 44 itoperates the valve which controls the guillotine ram a, which comes downwith a snap actionand severs the paper while the latter is still taut.At the same time, the tappet 44, through 4412 and 42b lifts the catch42a and releases the valve allowing the presser bar to rise. The mandrelmakes a further complete rotation to wind and roll on the end of thepaper while the striker head passes the space between the tappets 44 and45. Then the striker head 4I engages and operates the tapper 45 whichthrough its arm 45a. and trip arm 43c lifts the catch 43a and through43b, also lifts the catch 44a thus allowing the guillotine knife to riseand the pressure rollers I55 and I56 to lift off the mandrel. Thestriker head next engages the tappet 46 which operates the valve for theram 31a. This ram lifts the lug of the crosshead 3I out of the thread ofthe feed screw and the crosshead is then pulled back by its weight 39 tothe starting position as shown in Fig. 3. At the same time, the clutchis eased and the brake applied and the cam I30 is rotated so that thelever I00 can move into position for the nose I06 to be engaged by thelug I01. However, the lever I00 is not allowed to move into suchposition until the mandrel has slowed down sufficiently for the wheel 99of the governor to be drawn from under the lever 98 fixed to the leverI60. The clutch is set to drag the drum round slowly against the brakeand when the lug I07 engages the nose I06 it pushed down the extensionIOI until the stop lever I00 reaches the stop I04, the dash pot I05acting to check this movement. The downward movement of the extensionIOI also pulls down the catch end I09 which it had picked up when it wasreleased with the starting of the mandrel. The catch end I09 through thelink I I0 pulls down the lever I I I of the valve admitting pressure tothe ram I I2, the plunger I I4 of which engages with the stud H5 andoperates the levers 95 to collapse the mandrel. The downward movement ofthe plunger II4 also through the pin I23 engaging the catch end I24,operates the lever I25 of the valve which then admits pressure to theejector ram I31. The plate I47 engages the end of the carton which isnow hanging loose on the mandrel and pushes it off the end of themandrel. At the end of such movement of the ejector lug I49 engages thelever I48 to operate the valve I36 and restart the cycle of operation.The hydraulic pump is of course in operation the whole time to maintainthe pressure.

The mechanism could be operated by electric solenoids instead ofhydraulic rams and the valves would then be replaced by electric contactswitches.
